Por qué
El Gato es Muerto!

Hey Rojo-sy, try some ice cream for that bungo thing you got there.
and Redsy ate 'el gato' in that burrito he had.

So,

Anyway, before we get too carried away ...
Why does this diagram show an unswitched hot going up into the unit and why does the white (Blanco) wire from the left cable need a small jumper on it above? (2 wirenuts with jumper in between) ??

Bill

It appears to be a constant feed Bill, i can only think of a nite-light as a 4th entity.

I can't imagine why the 2 wire nuts are in series.

They even show ( in another of the generic instructions variations) the heat lamps & vent operating together.

How stupido!

Sparky,

I was wondering about a nite-lite too, but wouldn't that be on a switch?

Bill

Sparky,

I went to Nutone and found that this model is a Fan/Heat-Bulb fixture. That wasn't what I was originally referring to, but the wiring is still a mystery.

hmmmm,
have they a tech that would like to comment?

Uno questionne stupido, perhaps, but what is the physical arrangement of all the various items in these combo units?

We have combined fans/lights in a few places here (useful for the 2 days of summer we get each year!), but I've never seen one with a heater incorporated as well.

Two-Bulb Heat-A-Vent

• Two-Bulb Heat-A-Vent-Type IC
• It's a radiant heater and a vent, too.
• Uses 2 BR40/R40 infrared heat lamps or one incandescent lamp and one heat lamp (not included)
• 70 CFM ventilation, 3.5 sones
• Automatic reset for thermal protection

(from this page )

I usually see the ones with the resistive heating element >> 9965

Redsy:
A multi-wire circuit is a 3-wire edison, the nice thing about it is if you balance the loads the neutral carries no current.
The picture is the same one I saw yesterday at HD on a heat/vent/light unit a 3 switch deal, I posted the about that discovery but it never showed up.
The Nu-tone i saw friday at my supplier recomended a seperate 20 amp ccircuit. This is in addition to the mandated 20 amp circcuit for the bathroom. This is how i do it too. As i implied before I believe that two cables is in violation, even if I didnt Our inspectors insist that we use flex or MC Depending on how many switches are involved.
Three (3) switches we can use 12-4 MC cable and 4 switches flex, greenfield. I usually make up 2 or 3 ahead of time cut to different lengths just to have them on hand.
